Be it known that i, REUBEN MILLER, 51:, residing at Pittsburg, in the flaunt-y of Allegheuy and State (if icnusylva'nia, a citizen of the United States, have invented certain n and useful Improvements in Air-Valves for iug is a specification. reference being hull sh to fine accompanying drawing for explosive-engines, mid particularly a cmisti'uction and combination of as will be more fully hereinafter: (11% scrmcii, and pointed out in the claims.

The clieziper forms 01" gasangina are nm, E rule, provided with caruuretsrs wliiali e self-regulating fur all speeds; and the ob- 338i 0? my invsntion is in provide an mus air-valve which may be censtructecl at EXPGTSQ and may be attached its an t0 remedy this defect. is di' wings, Figure l shuws vertical se tic-n through the valve.

' starts better if the mixture is made richer than its expedient for fast running. Then when the engine speeds up the supplemem tary air-ports open, and on account of the spacing-of these ports the mixture is not only 'made'perfect in richness, but is so stirred u by the inrush of this additional air that it reaches the engine perfectly mixed for each explosion and constant for any speed of the engine.

What I claim as my mvention 1s 1. In an automatic valve, the combination .therein, a yielding member secured to said piston and tending to prevent movement thereof, a bell-crank lever pivoted in said casing and having one arm secured to the free endof said yielding member and adjusting means acting upon the other arm, for the purpose described.

3. In an. automatic valve, the combination with a casing having the apertures (L, the lever F, adjusting means K, spring G, and piston D having tapering apertures d, or the purpose described.

4. dnhn autonmtic air-valve the combinationiviisitlzt radially-apertured tubular member arranged in the gas -conduit efan engine, of a piston therein having radial apertures, said piston having a restrietedaxialaperture and being arranged toibe moved by. differential pressures of gas upon its ends to cause a registration of its radial apertures with those of. said tubular member, for the purpose described. V 1

5. In an automatic airvalve, the combination with a casing having its sides apertured,

T of a piston therein arranged to be moved by diiierential ressures of gas acting upon its opposite en s, and a yielding member tending to prevent said movement, said piston having apertures in its sides adapted to register with the aperturesin said casing, the

area of said registration'b'eing-in substan t-ia'lly constant ratio with the difference in pressure acting-upon said piston.

6. in an automatic air-valve, the combina-v tron with a casing having ts sides apertured,

of a piston therein arranged to be moved by 60 differential ressures of gasacti-ng upon its opposite on s, and a yielding member tending to prevent said movement, said pistonhavmgapertures in its sides adapted to register with the apertures in said casing, the area of said registration increasing dispro portionately to the increase of distance of movement of said piston, whereby the inconstant tension of said yielding member is substantially neutralized.

In testimony whereof I aflnr my signature I in presence of two Witnesses.
